how and why? keyed crank
How and why would you key the crank on an LS1? It seems the motor I bought has a key on the snout. (not the oil pump key! another one.) Can I just pop this key out and put my pully on since it is internally balanced or will this hurt it?

Re: how and why? keyed crank
The LS1 crank is not keyed where the balancer/pulley attaches. The balancer is pressed on. Thats ok for normal use, however, the folks that have a supercharger have found that the balancer/pulley will sometimes rotate on the crank end if the crank is not keyed.
If you not running a SC, it's not necessary to cut a keyway in the crank and balancer.
Ron,

The only key on your crank is the key that attaches the crank timing gear.
If you have a keyway that extends all the way out to the balancer, someone has modified it.
